Description
Technical field
The present invention relates to a kind of composite plant insecticide and preparation method thereof and application.
Background technology
Traditional Chinese medicine, grain and tobacco etc. often suffer damage by disease and insect at shelf time, lose huge.Utilization of pesticides is the means that modern insect protected is relatively commonly used, but traditional chemical insecticide usage amount is large, not only causes the pesticide resistance of insect, also causes serious environmental pollution and social influence, the agricultural chemicals remaining in reserve and storage equipment thereof exceeds standard, and directly affects health.Utilizing pollution-free, harmless plant is an important development direction of insecticide as insecticide, in recent years, has had many countries and enterprise in continuous research.
Utilize Invasive Alien Species to prepare the important measures that insecticide is modern agriculture, both realized the control to Invasive Alien Species, provide the new approach of producing to plant insecticide again.
Wherein, Eupatorium adenophorum, from composite family feverwort.From its stem, extract epifriedelinol; acetylate, the coumarinic acid of stigmasterol, positive octocosoic acid, β-Hu Luobu glucoside, 2-isopropenyl-5-acetyl group-6-hydroxyl benzofuran; except stigmasterol, remaining compound is all in Eupatorium adenophorum, to find first, and cauline leaf is all poisonous.
Fragrant eupatorium herb, from composite family feverwort.The chemical composition that separates, identifies from it has monoterpene, sequiterpene, diterpene, triterpene, phytosterol, flavones, coumarin, chromene, alkaloid, thymol derivative, acetophenone derivs, benzofuran derivatives and other phenolic acid compounds.From fragrant eupatorium herb, isolated compound does not also surpass and goes beyond the scope, mainly taking flavonoids, terpene and phytosterol as main, wherein Moham ' mad is in nineteen ninety-five isolated 2 ', 5-dimethoxy flavone is noval chemical compound, there is good repellent activity, also have certain allelopathic, insecticidal and antifungal effect.
Lantana, is China's second batch Invasive Alien Species, has huge prospect aspect control of insect, and a lot of agriculture and forestry insects are all had and significantly walked quickly and kept away and Antifeedant Effects.
But insecticide on market, inhibitor, pest repellant etc. are of a great variety, but properties of product differ, and effect is different, and the disease resistance of insect is constantly evolved, and single insecticide has been difficult to continue to play a role.
Summary of the invention
The object of the invention is to overcome the shortcoming of prior art, a kind of composite plant insecticide and preparation method thereof and application are provided, not only realize the function of desinsection but also can not cause environmental pollution.
The object of the invention is to be achieved through the following technical solutions: a kind of composite plant insecticide, it is prepared from by the batching of following weight ratio:
